Fix in Postman collection (Discover API)

In Discover API request from postman we use some enviromental variables to form the URL. More specifically the url is the following:

The {{INVOKER_ID}} variable is "?api-invoker-id=INV..."

When someone tries to insert new query parameters from Postman UI (in the Params tab), the parameters are added on the URL like that: https://{{CAPIF_HOSTNAME}}/{{DISCOVER_URL}}{{INVOKER_ID}}?api-name=...&aef-id=...

However character "?" is added 2 times and thus the request fails.

I think we shall either change the {{INVOKER_ID}} and "hardcode" the question mark in the URL or add api-invoker-id as a parameter from the beginning
